Concrete pouring formwork between Larsen steel sheet pile and steel enclosing purlin and construction method
The invention relates to the technical field of foundation pit supporting, and provides a concrete pouring formwork between a Larsen steel sheet pile and a steel enclosing purlin and a construction method.The concrete pouring formwork between the Larsen steel sheet pile and the steel enclosing purlin comprises a bottom formwork arranged in a notch, right facing the steel enclosing purlin, of the Larsen steel sheet pile, the bottom formwork abuts against the Larsen steel sheet pile and the steel enclosing purlin, and a pouring cavity with the bottom and the side portions closed is defined; the hanging bracket is arranged on the steel enclosing purlin in a sleeving mode, and an opening used for disassembling and assembling the hanging bracket is formed in the position, right opposite to a notch of the Larsen steel sheet pile, of the hanging bracket; and the pull rod is arranged at the opening of the hanging bracket, is movably connected with the hanging bracket and the bottom template, and is used for lifting the bottom template to abut against the steel enclosing purlin while closing the opening of the hanging bracket, or is used for lowering the bottom template while opening the opening of the hanging bracket so as to separate the bottom template from the steel enclosing purlin. The hanging bracket is arranged on the steel enclosing purlin, the hanging bracket is used as a formwork supporting piece, effective supporting of the formwork is achieved on the premise that the Larsen steel sheet pile structure is not damaged, and the construction efficiency is improved. And the construction cost is reduced.
本申请涉及基坑支护技术领域，提供了一种拉森钢板桩与钢围檩间混凝土浇筑模板及施工方法，包括：底模板、设置在拉森钢板桩的正对钢围檩的槽口内，且底模板与拉森钢板桩和钢围檩抵紧，合围形成底部和侧部封闭的浇筑腔；吊架，套装在钢围檩上，且正对拉森钢板桩的槽口处设置有用于吊架拆装的开口；以及拉杆，设置在吊架的开口处，活动连接吊架和底模板，用于封闭吊架的开口的同时提拉底模板抵紧钢围檩，或用于开启吊架的开口的同时下降底模板以分离底模板和钢围檩。本发明通过在钢围檩上设置吊架，利用吊架作为模板支撑件，在不破坏拉森钢板桩结构的前提下实现模板的有效支撑，提高了施工效率。降低了施工成本。
